Referring in detail to the drawings:

1 designates a show ease, in this instance a refrigerating display case being illustrated for which multiple panel windows are usually provided whereby the frosting of the panes due to moisture condensed thereon may be minimized.

2 designates a window frame, 3 an upper and 4 a lower casing thereof in which glass panels 5, 6 and 7 are to be installed. Three panels are here illustrated though the number may vary. f 1 I A back stop 8 of the lower casing is illustrated as a stop produced by the rabbeting of the casing to produce a groove 9 in which the panels are to `be positioned. A similar back stop 10 is associated with the upper casing 3 and it is understood that the sides or ends of the frame or opening of the show case are simby nails 19 in ,process of installation.

the installation of the window portions in the 1927. serial No. 203,411.

lower casing being discussed'. The sealing element comprises a plastic, flexible and adhesive substance preferably .having uncured rubber or similar'material as a base, and having relatively permanent resilient and adhesive qualities. A substance of the suggested composition is provided that will continue to adhere to both glass and wood and will preserve its sealing function under conditions of p expansion and contraction of the glass and Wood. l

The plastic material is laid in the casing grooves of top and ends also, to the thickness desired, for example, g inch, and against the faces of the back stops on the inner edge ofl the frame, the glass panel 5 is positioned in contact with the upturned vedge 12 and the body portion of the sealing element. Glazing strips or separators, such as 13 and 14, are positioned in contact with the sealing element and the surfaces of the panel 5 adjacent its outer edges, and the second panel 6 is installed in contact therewith whereby a chamber or enclosed space 15 is produced.l A second glazing strip,;sucl1 as 16, is installedv 75 as the separator between the second panel 6 and the third panel 7 the glazing strip being positioned by a -process illustrated in F ig. 4, to which specialA attention is called: yThe strip is held slantingly and its edge is pressed into the substance of the plastic material adjacent the edge of the panel `6; the strip is then pressed and established in horizontal position, whereby a portion 18 'of the plastic element 11 is pinched and protruded upward- 85 ly to constitute a flange or extension of the sealing element between the panel and the f strip. The strips may be secured to the frame The panel 7 which is the outer panel, hav- 90 y ing been positioned, the free edge of the sealingl element is pressed upwardas illustrated in Fig. 5, and laid against the outer face of the glass to produce theflange 20; and a finish stop 21 is installed to press the flange 20 in 95 Aposition and retain it, and to hold the assembled window in position. It is understood that similar. treatment of the 'sealing element 11 occurs with reference to the top an'dsides of the window to enclose and seal all edges 100.

of the outer panel, and finish stops are similarly installed.

" over the hygroscopic substance to retain .the same while permitting the functioning there,..-

vof through -said openings.

The structure having' been provided as described, the sealing element insulates the spaces enclosed by the panels and strips so that moisture may not enter thereinthrough the pores of the wood ofthe frame or around the edges of the glass panels, and exterior moisture is also retained aW'ay from the glazing strips which might conduct moisture in- 'to thejspaces. Such moisture as may have been present in the air trapped by the panels on initial establishment thereof, is attracted and withdrawn from the spaces by the hygroscopic element. The spaces being 'devoid of lmoisture, there isno .condensation on the surfaces of the panes within the enclosedspace and therefore, no frosting of the panels to obstruct the view therethrough.

The character of the sealing element which I designate is such that it is permanently able to maintain the seal. It is provided as l having permanent tensile strength so that a relatively large area maybe laid and will preserve its integritytunder distortion, and will nyieldto expansion ofthe panels; and, being relatively permanently viscous and retaining OVQI a long Vperiod the quality of adhesiveness, and also having a substantial degree of elasticity that persists, will mainftain' its contact with the contracting panels.

Should accident result in chance introducin position, portions of said plastic material being deflected between one of' said strips and one of said panels, and a portion of said plastic material being "upturned against the outer side of the outermost of said panels, and a stop iixed to the frame andl engaging said last-named portion of plastic material with said outer panel side. i

2. In a window, a frame having a rabbeted edgev a sealer comprising plastic material disposed'in the frame to receive the edges of glass panels, aplurality of panels positioned in said vplastic material, glazing strips spacing said panels, portions of said plastic material being distorted over adjacent face portions of the panels, and means fixing` the panels inposition.

3. In combination with a grooved window frame, a plurality of spaced panels, means for sealing the spaces between the panels comprising a flexlble element positioned in the groove of the window frame to receive the edges of the panels, a separator whereby a portion of the flexible element is inched into position between a panel and sald separator in the process of positioning said sepv arator, and means for` fixing the separator and panelsin posit'mn. 4. In a device of the character described,

a frame having a rabbeted edge, a sealer co1n'- prising lplastic material lcoverino` the inner 'surface lof the frame and extending continuously circumferentially and transversely` thereof, a plurality of panels positoned inV the' frame with their circumferential edges engaging the plastic material, means spacing said panels, portions of said plastic mav terial being distorted over outer adjacent free portions of the panelsua'nd means xing the tion of moisturetothespaces, the hygro-v scopic'element will absorby the moisture therei from.

of the referable use of an `element in powdered orm, portions of which 'might be imperceptibly'scatte ed, to be de osited on-the in a cloth bag or similarcontainer, and supplemental means lmay be'used as deslred, to

glass panels, a .plurality of panels having protect the material in installation.
